    Effects of treatment with oral appliance on 24-h blood pressure in patients with obstructive sleep apnea and hypertension: a randomized clinical trial2013Ingår i: Sleep and Breathing, ISSN 1520-9512, E-ISSN 1522-1709, Vol. 17, nr 2, s. 705-712Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Continuous positive airway pressure treatment has been shown to lower blood pressure (BP) in patients with obstructive sleep apnea (OSA). The aims of the present pilot study were to evaluate the potential effects of oral appliance (OA) therapy on BP, to assess various outcome BP measures, and to inform sample size calculation. Seventy-two patients with OSA and hypertension were randomly assigned to intervention with either an OA with mandibular advancement (active group) or an OA without advancement (control group). Before and after 3 months of treatment, the patients underwent nocturnal somnographic registration and 24-h ambulatory BP monitoring. Among the various BP measures, the largest trend toward effect of OA treatment was seen in 24-h mean systolic BP with a 1.8 mmHg stronger BP reduction in the active group compared with controls. A stronger trend toward effect was seen in a subgroup with baseline ambulatory daytime mean systolic BP > 135/85 mmHg where the mean systolic BP fell, on average, 2.6 mmHg. Additional exclusion of patients with baseline apnea hypopnea index (AHI) a parts per thousand currency sign15 gave a significant reduction in mean systolic BP of 4.4 mmHg (P = 0.044) in the active group compared with controls. In patients with OSA and hypertension, OA treatment had a modest trend toward effect on reducing BP. A stronger trend toward treatment effect was seen after excluding patients with normal baseline ambulatory BP. Additional exclusion of patients with baseline AHI a parts per thousand currency sign15 showed a significant treatment effect. Data to inform sample size for an adequately powered randomized study are provided.

    Improved quality and efficiency after the introduction of physician-led team triage in an emergency department.2016Ingår i: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 121, nr 1, s. 38-44Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Overcrowding in the emergency department (ED) may negatively affect patient outcomes, so different triage models have been introduced to improve performance. Physician-led team triage obtains better results than other triage models. We compared efficiency and quality measures before and after reorganization of the triage model in the ED at our county hospital.

    MATERIALS AND METHODS: We retrospectively compared two study periods with different triage models: nurse triage in 2008 (baseline) and physician-led team triage in 2012 (follow-up). Physician-led team triage was in use during day-time and early evenings on weekdays. Data were collected from electronic medical charts and the National Mortality Register.

    RESULTS: We included 20,073 attendances in 2008 and 23,765 in 2012. The time from registration to physician presentation decreased from 80 to 33 min (P < 0.001), and the length of stay decreased from 219 to 185 min (P < 0.001) from 2008 to 2012, respectively. All of the quality variables differed significantly between the two periods, with better results in 2012. The odds ratio for patients who left before being seen or before treatment was completed was 0.62 (95% confidence interval 0.54-0.72). The corresponding result for unscheduled returns was 0.36 (0.32-0.40), and for the mortality rates within 7 and 30 days 0.72 (0.59-0.88) and 0.84 (0.73-0.97), respectively. The admission rate was 37% at baseline and 32% at follow-up (P < 0.001).

    CONCLUSION: Physician-led team triage improved the efficiency and quality in EDs.

    The patient safety culture as perceived by staff at two different emergency departments before and after introducing a flow-oriented working model with team triage and lean principles: a repeated cross-sectional study2014Ingår i: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 14, s. 296-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Patient safety is of the utmost importance in health care. The patient safety culture in an institution has great impact on patient safety. To enhance patient safety and to design strategies to reduce medical injuries, there is a current focus on measuring the patient safety culture. The aim of the present study was to describe the patient safety culture in an ED at two different hospitals before and after a Quality improvement (QI) project that was aimed to enhance patient safety. Methods: A repeated cross-sectional design, using the Hospital Survey On Patient Safety Culture questionnaire before and after a quality improvement project in two emergency departments at a county hospital and a university hospital. The questionnaire was developed to obtain a better understanding of the patient safety culture of an entire hospital or of specific departments. The Swedish version has 51 questions and 15 dimensions. Results: At the county hospital, a difference between baseline and follow-up was observed in three dimensions. For two of these dimensions, Team-work within hospital and Communication openness, a higher score was measured at the follow-up. At the university hospital, a higher score was measured at follow-up for the two dimensions Team-work across hospital units and Team-work within hospital. Conclusion: The result showed changes in the self-estimated patient safety culture, mainly regarding team-work and communication openness. Most of the improvements at follow-up were seen by physicians, and mainly at the county hospital.

    Physician-led team triage based on lean principles may be superior for efficiency and quality?: A comparison of three emergency departments with different triage models2012Ingår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, ISSN 1757-7241, E-ISSN 1757-7241, Vol. 20, nr 1, s. 57-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    The management of emergency departments (EDs) principally involves maintaining effective patient flow and care. Different triage models are used today to achieve these two goals. The aim of this study was to compare the performance of different triage models used in three Swedish EDs. Using efficiency and quality indicators, we compared the following triage models: physician-led team triage, nurse first/emergency physician second, and nurse first/junior physician second.

    METHODS:

    All data of patients arriving at the three EDs between 08:00- and 21:00 throughout 2008 were collected and merged into a database. The following efficiency indicators were measured: length of stay (LOS) including time to physician, time from physician to discharge, and 4-hour turnover rate. The following quality indicators were measured: rate of patients left before treatment was completed, unscheduled return within 24 and 72 hours, and mortality rate within 7 and 30 days.

    RESULTS:

    Data from 160,684 patients were analysed. The median length of stay was 158 minutes for physician-led team triage, compared with 243 and 197 minutes for nurse/emergency physician and nurse/junior physician triage, respectively (p < 0.001). The rate of patients left before treatment was completed was 3.1 % for physician-led team triage, 5.3 % for nurse/emergency physician, and 9.6 % for nurse/junior physician triage (p < 0.001). Further, the rates of unscheduled return within 24 hours were significantly lower for physician-led team triage, 1.0 %, compared with 2.1 %, and 2.5 % for nurse/emergency physician, and nurse/junior physician, respectively (p < 0.001). The mortality rate within 7 days was 0.8 % for physician-led team triage and 1.0 % for the two other triage models (p < 0.001).

    CONCLUSIONS:

    Physician-led team triage seemed advantageous, both expressed as efficiency and quality indicators, compared with the two other models.

    Waiting management at the emergency department - a grounded theory study2013Ingår i: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 13, s. 95-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: An emergency department (ED) should offer timely care for acutely ill or injured persons that require the attention of specialized nurses and physicians. This study was aimed at exploring what is actually going on at an ED. Methods: Qualitative data was collected 2009 to 2011 at one Swedish ED (ED1) with 53.000 yearly visits serving a population of 251.000. Constant comparative analysis according to classic grounded theory was applied to both focus group interviews with ED1 staff, participant observation data, and literature data. Quantitative data from ED1 and two other Swedish EDs were later analyzed and compared with the qualitative data. Results: The main driver of the ED staff in this study was to reduce non-acceptable waiting. Signs of non-acceptable waiting are physical densification, contact seeking, and the emergence of critical situations. The staff reacts with frustration, shame, and eventually resignation when they cannot reduce non-acceptable waiting. Waiting management resolves the problems and is done either by reducing actual waiting time by increasing throughput of patient flow through structure pushing and shuffling around patients, or by changing the experience of waiting by calming patients and feinting maneuvers to cover up. Conclusion: To manage non-acceptable waiting is a driving force behind much of the staff behavior at an ED. Waiting management is done either by increasing throughput of patient flow or by changing the waiting experience.

    The impact on quality of life of different symptoms from the lower urinary tract in men measured by the SF-36 questionnaire2006Ingår i: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 40, nr 6, s. 485-494Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective. To describe how different lower urinary tract symptoms (LUTS) affect the quality of life (QOL) in men. Material and methods. The study included 1008 men aged 40-80 years living in the community of Surahammar, Sweden who had answered a questionnaire concerning stress incontinence, urgency and post-micturition dribbling 12 months earlier. The occurrence and severity/frequency of 12 specific LUTS were assessed using the Danish Prostatic Symptom Score questionnaire. QOL was evaluated using the Short Form 36 (SF-36) questionnaire. Results. Post-micturition dribbling was the most frequently reported symptom (71%) and stress incontinence the least common (11%). Men who experienced urge, stress or "other incontinence'' had lower mean scores for all of the eight dimensions measured by the SF-36 than men without such symptoms. Furthermore, men who experienced a moderate/severe degree of weak stream or nocturia reported a poorer QOL for all dimensions compared to men with a mild level of the same symptoms. QOL was found to decrease with increasing age. Men aged 66-80 years with "other incontinence'' reported lower mean SF-36 scores for physical functioning, role physical, role emotional, social functioning and body pain than 40-65-year-old men. Conclusions. LUTS in men affect QOL dimensions differently. Storage symptoms appear to reduce QOL more than voiding and post-micturition symptoms. Urinary incontinence affected all eight of the dimensions evaluated. Elderly men with LUTS reported a lower QOL than younger men.

    4-year follow-up of treatment with dental appliance or uvulopalatopharyngoplasty in patients with obstructive sleep apnea: A randomized study2002Ingår i: Chest, ISSN 0012-3692, E-ISSN 1931-3543, Vol. 121, nr 3, s. 739-746Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Study objectives: To evaluate the effects of treatment with a dental appliance or uvulopalato-pharyngoplasty, (UPPP) on somnographic variables in patients with mild-to-moderate obstructive sleep apnea (OSA) followed up for 4 years, and compliance,and complementary treatment.

    Design: Randomized study.

    Setting: Central Hospital, Västerås, Uppsala University, Sweden.

    Patients: Ninety-five male patients with confirmed mild-to-moderate OSA (apnea index (AI) > 5 and < 25) were randomized to treatment with a dental appliance or UPPP. Sleep studies were performed before and 1 year and 4 years after intervention. Thirty-two patients in the dental-appliance group and 40 patients in the UPPP group completed the 4-year follow-up.

    Results: The success rate (percentage of patients with at least 50% reduction in AI) in the dental-appliance group was 81%, which was significantly higher than in the UPPP group, 53% (p < 0.05). Normalization (AI < 5 or apnea/hypopnea index < 10) was observed in 63% of the dental-appliance group and 33% of the UPPP group after 4 years. The difference between the groups was significant (p < 0.05). The compliance to use of the dental appliance was 62% at the 4-year follow-up. Thirty patients (75%) in the UPPP group continued without complementary treatment. The dental appliances had few adverse effects on the stomatognathic system, and the number of adjustments and repairs of the appliances over time was moderate. Pronounced complaints of nasopharyngeal regurgitation of fluid and difficulty, with swallowing after UPPP were reported by 8% and 10%, respectively.

    Conclusions: The dental-appliance group showed significantly higher success and normalization rates regarding the somnographic variables compared to the UPPP group, but the effectiveness of the dental appliance was partly invalidated by the compliance of 62% at the 4-year follow-up. However, the appliances had few adverse effects on the stomatognathic system an required only moderate adjustments. Use of a dental appliance with regular follow-up can be recommended for long-term treatment of OSA.
