Attention focus, trait anxiety and pain perception in patients undergoing colposcopy

The Effect of Forced Cough to Minimize Pain and Discomfort at the Time of Colposcopy-Guided Cervical Biopsy

OBJECTIVE

The aim of the study was to determine whether forced cough during colposcopy-guided cervical biopsy affected pain and anxiety levels.

MATERIALS AND METHODS

The study was conducted at the University Hospital (Newark, NJ) Ambulatory Care Center from December 2016 to June 2018 and evaluated 110 patients at the time of a colposcopy-guided cervical biopsy. Study patients were randomized to either cough or no cough group during the biopsy procedure. Pain level was assessed using a visual analog pain scale before, during, and immediately after a colposcopy-guided cervical biopsy. Study patients also completed a standardized anxiety survey before and after the procedure. T tests, Pearson χ, or Cochran-Mantel-Haenszel were used to compare baseline characteristics between the cough and no cough groups. Multivariate linear regression analysis was used to identify potential confounders and then compare pain levels across both groups.

RESULTS

There was no statistically significant difference in pain scores between the cough and no cough group when analyzed for each demographic variable even when confounders were accounted for. The anxiety scores for both study groups before and after the procedure were similar and not significantly reduced.

CONCLUSIONS

We observed a trend that cough reduced pain associated with the colposcopy-guided cervical biopsy but did not reach statistical significance. A similar outcome was observed in anxiety level, where anxiety was reduced in the cough group but was not statistically significant as compared with the no cough group. Further studies are necessary to assess various modalities in reducing pain and anxiety associated with colposcopy-guided cervical biopsy.

Virtual reality distraction induces hypoalgesia in patients with chronic low back pain: a randomized controlled trial

Background

Attentional distraction from pain has been shown to be largely ineffective for obtaining a hypoalgesic effect in patients with chronic pain when compared to a control condition. It has been hypothesized that this may be due to the non-engaging types of distraction that have been used so far. Moreover, it is suggested that the hypoalgesic effects of distraction may be attenuated by pain-related cognitions and emotions, as they may increase the attention to pain.

Methods

In this randomized controlled trial, patients with chronic nonspecific low back pain in the intervention group (n = 42) performed a single exercise session with nonimmersive VR games, while those in the control group (n = 42) performed the same exercises without VR games. We investigated whether VR distraction had a hypoalgesic effect during and immediately after the exercises, and whether it reduced the time spent thinking of pain during the exercises. We further explored whether pain-related fear, pain catastrophizing and baseline pain intensity moderated the effects of VR distraction.

Results

VR distraction had a hypoalgesic effect during (Cohen’s d = 1.29) and immediately after (Cohen’s d = 0.85) the exercises, and it also reduced the time spent thinking of pain (Cohen’s d = 1.31). Preliminary exploratory analyses showed that pain-related fear, pain catastrophizing and baseline pain intensity did not moderate the effects of VR distraction.

Conclusions

Large effect sizes of VR distraction induced hypoalgesia were observed. This suggests that nonimmersive VR games can be used when it is deemed important to reduce the pain during exercises in patients with chronic nonspecific low back pain.

Exploring women's sensory experiences of undergoing colposcopy and related procedures: implications for preparatory sensory information provision

INTRODUCTION

Some women experience distress during colposcopy examinations which is partly related to women's fear, or experience, of pain during the procedure. However, little is known about women's sensory experiences of colposcopy (other than pain) or what might impact on these experiences. The aim of this study was to explore women's sensory experiences of colposcopy and related procedures and identify factors which influenced negative sensory experiences.

METHODS

In-depth interviews were conducted with 23 women who had undergone, for the first time, a colposcopy (some with related procedures, including punch biopsies and loop excision) as part of follow-up for abnormal cervical cytology. Interviews were analysed thematically using the Framework Approach to organise the data and identify emerging higher-order themes.

RESULTS

Women described a range of sensory experiences including pain or discomfort, cramping, stinging and cold sensations (due to the application of acetic acid to the cervix). Four key themes emerged as important aspects of the overall sensory experience: levels of pain, treatment-specific sensations, anaesthetic-specific sensations and solution-specific sensations. Factors that may influence women having a negative sensory experience were sensory expectations of the procedure(s) and lack of preparatory sensory information.

DISCUSSION

Our study provides unique in-depth insight into women's sensory experiences of colposcopy and related procedures and suggests women require more preparatory sensory information. The issues identified as contributing to women having a negative sensory experience may help inform the development of pre-colposcopy information which may better prepare women with abnormal cervical cytology for follow-up examinations.

Multidimensional associations of pain and anxiety before and after colposcopy

OBJECTIVE

To assess the effect of pre-procedural variables on post-procedural outcomes following colposcopy.

METHODS

A prospective study was conducted at Concord Women's Health Center in Israel between March 1, 2013, and March 31, 2014. Women waiting for colposcopy were approached and asked to complete questionnaires about anxiety, information-seeking patterns, fear associated with the examination, and demographics. After the procedure, participants answered questions about pain and state anxiety. The physician performing the procedure assessed the participant's levels of distress. A path analysis model was constructed.

RESULTS

Path analysis showed direct and indirect effects of both demographic and psychological variables on the main outcome measures. Physician's appraisal was related to fear, information seeking, state anxiety, and pain. Post-procedural state anxiety was related to fear, trait anxiety, pre-procedural state anxiety, past experience, pain, and information seeking. Pain was related to information seeking and age. Information seeking, pre-procedural state anxiety, and subjective pain served as mediators for some of these relationships.

CONCLUSION

The effect of various psychological and demographic variables on psychological outcome variables following colposcopy should not be measured independently but rather as inter-related variables.
