Anxiety disorders in patients with COPD: a systematic review.

BACKGROUND: There is a growing interest in the role of comorbid anxiety in patients with COPD. Comorbid anxiety has a major impact on physical functioning, health-related quality of life, and healthcare utilization. However, the prevalence of clinical anxiety, particularly specific anxiety diagnoses, in patients with COPD remains unclear. OBJECTIVE: We performed a systematic review of studies that report the prevalence of clinical anxiety and specific anxiety disorders in patients with COPD. METHODS: We searched for articles in CINAHL, EMBASE, MEDLINE, and PsycINFO, from 1966 to January 31, 2012, with a focus on studies that utilized clinical interviews for a robust psychiatric diagnosis in patients with COPD. RESULTS: Of 410 studies identified, 10 met the inclusion criteria for review. The studies had small to modest sample sizes (n = 20-204) and included mainly male COPD subjects (71% male). The prevalence of clinical anxiety ranged from 10-55% among in-patients and 13-46% among out-patients with COPD. The reported prevalence of specific anxiety disorders ranged considerably, and included generalized anxiety disorder (6-33%), panic disorder (with and without agoraphobia) (0-41%), specific phobia (10-27%), and social phobia (5-11%). Women were significantly more likely to have a clinical anxiety disorder, particularly specific phobia and panic disorder. CONCLUSIONS: There is a high prevalence of clinical anxiety in patients with COPD. Social phobia and specific phobia appear to be particularly prevalent, yet they have received little attention within existing literature. Further research into effective management and screening for clinical anxiety disorders is warranted.

Relationship between anxiety, depression, and quality of life in adult patients with cystic fibrosis.

BACKGROUND: The impact of anxiety and depression on quality of life (QOL) in adult patients with cystic fibrosis (CF) is fully unknown. We investigated the prevalence and factors associated with anxiety and depression, including QOL, in adult CF patients. METHODS: One hundred twenty-one adult CF subjects, age ≥ 18 years were recruited from our out-patient clinic. Participants self-completed the Hospital Anxiety Depression Scale and the Cystic Fibrosis Quality of Life Questionnaire (CF-QOL). Socio-demographic data and values for lung function were extracted from the medical notes. RESULTS: Mean ± SD age was 30 ± 8.8 years, and age ranged 18-70 years. Forty (33%) were identified with anxiety symptoms, 20 (17%) with depressive symptoms. Factors related with depression were impaired QOL and low lung function. Anxiety was associated with difficulty in interpersonal relationships and severity of chest symptoms. The CF-QOL sub-domains (physical functioning, social functioning, treatment issues, chest symptoms, emotional functioning, concerns for the future, interpersonal relationships, body image, future/career concerns, and total CF-QOL) were all significantly correlated with anxiety (P < .001) and with depression (P < .001), respectively. CONCLUSIONS: Anxiety and depressive symptoms are common in adult CF patients. They are associated with poorer QOL, low lung function, reduced physical functioning, and severity of chest symptoms. Therefore, routine screening for symptoms of anxiety and depression is a worthy endeavor, and those identified with elevated clinical symptoms should be referred to receive appropriate treatment.

Tiotropium for treatment of stable COPD: a meta-analysis of clinically relevant outcomes.

OBJECTIVE: To systematically review recent evidence on the effectiveness of tiotropium versus placebo, ipratropium, and long-acting ß(2) agonists on outcomes relevant to patients with stable COPD, including health-related quality of life, dyspnea, exacerbations and hospitalizations. METHODS: Our inclusion criteria for trials were: ≥ 12 weeks; compared tiotropium to placebo, ipratropium, or long-acting ß agonists; patients ≥ 40 y old and with stable COPD. Sixteen trials (16,301 patients) met the inclusion criteria. RESULTS: Tiotropium improved health-related quality of life (measured with St George's Respiratory Questionnaire) compared to placebo (odds ratio [OR] 1.61, 95% CI 1.38-1.88, P < .001) and ipratropium (OR 2.03, 95% CI 1.34-3.07, P = .001). Tiotropium also improved dyspnea (measured with the Transitional Dyspnea Index) compared to placebo (OR 1.96, 95% CI 1.58-2.44, P < .001) and ipratropium (OR 2.10, 95% CI 1.28-3.44, P = .003). Tiotropium decreased the likelihood of an exacerbation (OR 0.83, 95% CI 0.72-0.94, P = .004) and related hospitalizations (OR 0.89, 95% CI 0.80-0.98, P = .02) but not serious adverse events (OR 1.06, 95% CI 0.97-1.17, P = .19), compared to placebo. The cumulative incidence of dry mouth was 7.4% with tiotropium, compared to 3.9% with ipratropium, 1.6% with salmeterol, and 2.0% with placebo. CONCLUSIONS: In stable COPD, tiotropium showed superior efficacy in improving quality of life and dyspnea, compared to placebo and ipratropium. However, tiotropium's differences with salmeterol were less clear.

Falls in people with learning disabilities: what are the risk factors and prevention strategies?

There is a high prevalence of falls and related injuries in adults with learning disabilities. This article highlights the latest evidence on the diverse risk factors for falls among this group. Research into effective falls management strategies is sparse, but there is some evidence to indicate that environmental management, strength and balance training, and careful management of medications may help to reduce falls. Nurses can play an important role by identifying those who are at most risk, implementing management strategies and educating others.
